<pre>I tested this Samsung TV with an AMD Athlon 200GE (Raven Ridge) system and
there were no issues in UHD Color mode. Note that AMD driver default to YCbCr
422/444 in all 4K modes.
Now I'm 90% sure that in "high speed" 594 Mhz HDMI modes those Samsung TVs
expect YCbCr rather than RGB. We need an option to to make the color space
switchable and not limited to RGB. RGB is obviously not the best option for
some displays.</pre>
